Worth a try. If it doesn’t work I think the e-tube software would install the right firmware to get everything working together.

I think firmware upgrades are the problem, I think mix and match 10sp and 11sp was allowed in early versions and then Shimano banned it as they realised the loophole meant you didn’t need a full new group for 11sp upgrades

Not for shifters. Every Di2 shifter ever was compatible with modern setups last time I checked.
